ABSTRACT
A vulnerable zone to nitrates pollution has been delineated at the
Prefecture of Imathia, northern Greece. An action plan has been
formulated, targeting surface and groundwater protection from nitrates,
in compliance with the nitrates directive 91/676/EEC and the regulation
1257/99/EC. The plan comprises measures and practices and is linked to
the Code of Good Agricultural Practice. The latter assists the farmers
in achieving maximum effectiveness of N fertilisation and irrigation by
means of environment-friendly techniques. It suggests a maximum
admissible application of nitrogen fertilisation for main crops, taking
into account the soil type, climatic regime, irrigation method and
hydrogeological conditions. According to this plan, a substantial
reduction of N fertilisers is achieved for cotton and an even a higher
decrease (30-40%) is suggested for corn.
Key Words: nitrates; vulnerable zone;
soil; groundwaters.
